MECHATRONIC DEVICE Russian patent published in 2015 - IPC H02K19/06 H02K21/00 H02K7/10 

FIELD: electricity.

SUBSTANCE: invention is related to the area of electric engineering and may be used in electric drives of different mechanisms and actuators of automatic systems. Mechatronic device comprises synchronous motor with concentrated windings at stator poles with number of poles multiple to number of alternating current phases, winding-free rotor. Stator and rotor are made composite and consisting of two cylindrical core stacks with scalloped surface and even pitch. Number of teeth at rotor is less than number of teeth at stator. Stator packs are turned towards each other, at that angle of their scalloped surfaces shear is equal to 180°. Between core stacks of stator there is permanent magnet with axial magnetisation. Rotor is set in stator bore and may perform the following complicated movement: precession in regard to stator axis and rotary in regard to own axis of symmetry. In order to transmit rotary movement of rotor to output shaft there is a device transmitting offset rotary movement, for example a pivoting device or an elastic deformable link.

EFFECT: reduced level of torque pulsation, increased reduction ratio and expanded functional capabilities.
